IMPROVEMENT IN HAND-POWER LOONIS.

i Specification forming part of Letters Patent No. 63,143, dated March26, 1867.

l To all .whom it may concern:

Be it known that we, J. M. DEEN, W. B. BOLDING, and H. PERRY, all ofDayton, in the county of Washington and State of Iowa, have inventedcertain new and useful Improvements in Hand-Power Looms; andy we dohereby declare the following to be afull, clear, and exact descriptionof the same, sufficient to enable one skilled in the art to which theinvention appertains tol make use of it, reference being'had to theaccompanying drawings, l

which form a part of this specification, and in which- .v

Figure l is a plan or top view of our improved hand-power loom. Fig. 2is a sectional Ielevation on the line w ofv Figs. 1, 3, and 4.

Fig. 3 is an end elevation. Fig. 4 is a section on the line XI XI ofFigs. l and 2. Fig. 5 is a section in XII XII of same figures.

In all the figures like parts are indicated by the same letters ofreference.

j The nature of our inventionconsists in so constructing and arrangingthe mechanism of a hand-power loom that the operation of the treadlesand the consequent shifting of the harness, the necessary movement ofthe pickerstaffs to insure the effective' throw of the shuttle, and therevolution of the cloth-beam to take up the fabric as it is woven, shallbe goveredby the action of the batten, and be at all times within thecontrol of the weaver.

In the drawings, A A A' Al are the posts and beams constituting theframe of a handpower loom. A is the breast-beam. B is the batten, alongthe upper lsurface of which is the shuttle-race, terminating at each endof the batten in a tube or gallery, into which the shuttle isalternately thrown. l'

A handle, B', is constructed on the top of the batten for convenience inoperating.

The batten is sustained by two standards, C C, attached at the lowerends to, and free to vibrate with, the rock-shaft D D, having theirbearings in the beams A' A of the frame, through which they extend to adistance nearly equal to the length of the batten.

To the under side of the batten is jointed a connecting-rod, E, which isjointed at its other end to the lever F by the joint-pin c.

The lever F has its fulcrum on the under side of the breast-beam A, andat its lower end is jointed to one end of the lever Gr. The other end ofthe lever G is jointed to a bridle carrying afeed-hand, b. (See Figs. 3and 4.) This feed-hand gives motion to a ratchet-wheel, c, having itscircumference divided into from three to six teeth.

.The ratchet-wheel c is fast upon ashaft,

`v vhichmaycarry from threeto .six pairs of wipers, d, furnished'attheir Yextremities with friction-rollers. Y

The treadles H Hvibrate on the shafte, and are moved alternately by thewipers d as these, in their revolution, come in contact with the innerends of the/treadles, which may also be from three-to six in number, tosuit the requirements of dierent fabrics.

The ends of the treadles opposite to the wipers are arcs of a circle,having'theircenter at c and attached to each treadle is a strap, f, theupperends of which. straps are attached to the harness-frame, a frame toeach treadle. The. frames themselves are connected by a strap, g, whichpasses from one, over a pulley or shaft, to the other.

It will be evident that as the inner end of one treadle is lifted by itswiper,-the harnessframe that is attached toit will be pulled down, andthe otherharnessfraine will be pulled' up by the strap g, the .strapf onthe liftedl frame causing the inner end of its treadle to be depressedso as to be'operated in turn by its wiper. This movement, it will beseen, must take place while the batten is being vibrated toward thebreast-beam, the position of the harness-frames being, unchanged. bymoving the batten toward them.

The rock-shafts D D support at their extremities the picker-staffs I I,which are jointed to the rock-shaft, so as to have a vibratory motion inthe plane of the axis ofthe rock-shaft as well as with the batten. l

' The picker-sta's project up into the galleries or shuttle-boxestat theends of the batten, and are each attached to a block, which moves withthem to and fro in the boxes. The picker-.staffs are each also connectedby a slack strap or cord to the tumblers K K. These tumblers are soattached to the standardsl O O as to vibrate upon centers h, and projecteach of their hooked ends through an opening in each of the standards,or be thrown in toward the operator. Their office is to cause thepicker-staffs to throw the shuttle alternately from one side to theother of the loom, and they are operated as follows:

To each of the standards C is attached, by a joint, a lever, L,connected at vits other eX- tremity with a bridle and feed-hand, i,which give motion to the shaft M through the ratchet N, each of which isdivided into four teeth. At each end of the shaft M is an arm, N, of

two limbs, the arm at one end being placed at right angles with the armat the other end. The teeth of the ratchet and the feed-hand are soarranged that the shaft M is caused to make a quarter-revolution eachtime that the batten is moved toward the harness, and the arms are soset on the shaft th at one end of each of them alternately is brought upin close proximity to the outer face of one of the standards C, andunder the hooked end of a tumbler, K. This is made to happen just beforethe batten has arrived at the end of its vibration toward the harness,when the nal movement of the batten causes the arm to quicklythrow thetumbler in toward the operator, the strap or cord which is attached tothe picker-staf causing, by a sudden jerk, the block in the shuttlc-boxto strike smartly against the shuttle,

driving it through the warp to the other end of the shuttle-race, whereit comes in contact with the head of the other picker-stam which itforces to the end, and, through the slack strap or cord, causes theother tumbler, K, to resume a position to bemacted on by the arm N onthe other end of the shaft M the next time that the batten is movedtoward the harness, when the operation will be repeated as iirstdescribed.

The roller or cloth-beam on which the woven material is received as itis completed is furnished with a ratchet, operated by a feed-hand,

K.. This feed-hand may be made adjustableon the end of a lever, l,having its fulcrum at on, which lever, in turn, is connected by ajointed link to the bar n, made adjustable on one of the standards C bymeans of a slot and set-screw, o. It will be seen that as the distancefrom the inner end of the lever l to the center of motion of thestandard C is increased or diminished by the bar 'n and set-screw o, sowill the amount of motion vary that may be given to the cloth-beam.- Thefeeding occurs while the batten is moving toward the breast beam.

the warp is carried through the harness, are each kept from turning toofreely, or fromia liability to turn back, by pressure from a strap,which, secured firmly at its lower end to the frame-work of the loom,passes over or around a collar on the shaft and roller, and is attachedto a weight or spring by its other end.

The movement of the batten toward the breast-beam actuates the treadlestol shift the harness,and causes the woven fabric to be gathered on theroller that receives it, while the movement toward the harness causesthe picker-staffs at the end of the movement to drive the shuttle on itserrand, which it acp complishes while the batten is at rest,`and, beforeit returns toward the breast-beam.

At each end of the shuttle-race is a dumblatch, Q, (see Figs. l and 2,)which, being pivoted onl its center, is so operated by the head of' thepicker-staff, when the shuttle strikes against it, as to catch againstthe side of theV shuttlel as it arrives at the end of 'its throw, andholds it so that it cannot rebound or move until it is struck again bythe head of the picker-staff to be sent back.

Having described our invention, what we claim therein as new, and desireto secure by Letters Patent, is-

1. Operating the treadles `H H by means of the levers F and G, jointedconnecting-rod E, the feed-hand b, and ratchet c, with the wipers d,arranged and combined with the 'hatten B, in the manner and forthepurpose set forth.

2. The levers L, feed-hand t', shaft M, and arms N, in combination withthe tumblers K, picker-staifs I I, and batten B, substantially as andfor the purpose set forth.
